DL8系列 Functions
Data can be uploaded to a cloud server or a PC by FTP, so that multiple users can access it at once without overloading the local DL8 module. Local data logging in CSV format is available by using an SD card memory, thus the DL8 functioning as a stand-alone data logger.
Each signal channel is available with alarm threshold setting to trip alarm contact outputs by adding discrete output modules for buzzers and lamps. E-mailing with a preset message attached with event data is also possible. Mails can be used for regular reporting purposes, too.
At the maximum of 32 analog signals, 64 each of discrete inputs and outputs, and 32 pulse signals can be handled by one DL8 module. The remote I/O model R7E, R3-NE1 and other Modbus/TCP slaves can be connected. Modbus RTU devices such as Multi Power Monitor L53U are connected through a gateway unit (Model: GR8-EM). I/O data is assigned by using only general address information (IP address, node number and channel), so that other manufacturers' I/Os are also usable.
The DL8 functions as Modbus master to collect data from remote I/O, while it functions as Modbus slave when a supervisory monitoring system (SCADA) polls data of the DL8.

I/O Marshalling
Advanced View |
 |
Input at one I/O module can be output at another connected over Modbus/TCP network, by simply specifying combination of Di/Do and Ai/Ao. |
